She has one of the most recognisable faces around, having been part of one of the first ever reality TV shows The Osbournes – but fans still struggled to spot Kelly Osbourne in a picture she shared this weekend.
In a post on Instagram, the star, 36, showed off a new hairstyle, with her purple locks fashioned into neat 'space buns'.
However, it wasn't her do' that caught the attention of social media users – but the results of her dramatic weight loss.
However, Osbourne's latest snap – which has garnered more than 119,000 'likes' – appears to have amazed fans all over again.
Among the celebrities to comment was Fearne Cotton, who wrote: "Beautiful."
Many followers were quick to point out that her transformation was such that they hardly recognised her.
One shared "I didn't even recognise her!!" while another noted "this doesn't even look like Kelly?" and a third added: "Who’s that girrrrl?"

Earlier this month, Osborne opened up about suffering a relapse during the pandemic after being four years sober of drugs and alcohol.
She explained in an interview on Dax Shepard's Armchair Expert podcast that after being fine having one drink, a couple of weeks later she ended up having much more alcohol and did "embarrassing sh**. Blacked out."
Last summer, Osbourne posted another picture to Instagram of herself wearing a red Gucci boiler suit from the backseat of a taxi.
She received a comment from TV star Olivia TuTram Mai, who wrote: “Oh my gosh, you lost a lot of weight.”
In response, Osbourne explained: "That’s right mamma Mai I lost 85lbs since I last saw you. Can you believe it? Kaakakaka.”
On her Instagram Story, she also shared a photo of an old Neiman Marcus clothes tag from a size 26 garment.
The star captioned it: “Yes... I’m bragging because I worked so hard and it feel good!!!”
She previously slimmed down after appearing on TV show Dancing With The Stars in 2009, during which she lost just over 2st.
